Job Description

Principal Mixed?Signal Hardware Engineer (Scientific Instruments)
Join LECO in St. Joseph, Michigan--an 80+ year, family?owned innovator in world?class laboratory instrumentation. We value long?term stability, loyalty, trust, and shared purpose, and our products support scientists around the globe.
Schedule: Monday-Friday, 8:00 a.m.-5:00 p.m., on?site
A day in the life
You'll start your morning reviewing your engineering notebook and latest test data from a precision measurement board. By midday, you're collaborating with mechanical and software peers to refine a subsystem architecture for a next?generation instrument. In the afternoon, you'll implement design updates, run bench evaluations, and capture findings for design reviews--operating with a high degree of technical independence throughout.
Role overview
As a senior engineer, you will own the design of advanced electrical components and sub?assemblies with minimal oversight. You will report to the Manager, Electronics Research & Engineering, or the Manager, RF Products.
What you'll own

• End?to?end design of electrical components and sub?assemblies, from concept through release
• Researching, building, and testing prototypes to validate performance
• Diagnosing and resolving production issues in partnership with manufacturing
• Authoring and maintaining design artifacts (schematics, BOMs, specifications) and keeping a logbook
• Preparing documentation packages for formal design reviews
• Contributing within cross?disciplinary teams while accounting for system?level tradeoffs
• Investigating emerging technologies to drive product innovation
• Leading specialty electrical design efforts independently

What you bring

• Depth across a broad spectrum of electrical engineering topics, including:

• Mixed?signal design (ADC/DAC) for precision measurement systems
• Microcontroller?based hardware design
• Analog circuit design
• Closed?loop temperature control
• AC power design (single?phase and three?phase)
• High?voltage design (?1 kV, typically low power)
• Motor control
• Human?machine interface (HMI) design
• System?level architecture
• PCB/PWB design and PWA practices
• Wire harness design
• Clear written and verbal communication with strong documentation discipline
• Effective collaboration and facilitation skills; sensitivity to multi?disciplinary stakeholder needs
• Awareness of design impacts across the broader team and product lifecycle

Education & experience

• Master's degree, or Bachelor's degree with substantial related experience
• 7+ years of relevant, hands?on electrical engineering experience

Reporting
This role reports to the Manager, Electronics Research & Engineering, or the Manager, RF Products.
